Important Service Information

RoHS (2002/95/EC) Requirements – Applied to all countries require RoHS.

The RoHS (Restriction of Hazardous Substance in Electrical and Electronic Equipment Directive) is

a legal requirement by EU (European Union) for the global electronics industry which sold in EU

and some counties also require this requirement.Any electrical and electronics products launched in

the market after June 2006 should meet this RoHS requirements.Products launched in the market

before June 2006 are not required to compliant with RoHS parts.If the original parts are not RoHS

complaints, the replacement parts can be non ROHS complaints,but if the original parts are RoHS

compliant, the replacement parts MUST be RoHS complaints. If the product service or maintenance

require replacing any parts, please confirming the RoHS requirement before replace them.

Safety Notice

4

1. Make sure your working environment is dry and clean, and meets all government safety

requirements.

2. Ensure that other persons are safe while you are servicing the product.

3. DO NOT perform any action that may cause a hazard to the customer or make the product

unsafe.

4. Use proper safety devices to ensure your personal safety.

5. Always use approved tools and test equipment for servicing.

6. Never assume the product’s power is disconnected from the mains power supply. Check that it

is disconnected before opening the product’s cabinet.

7. Modules containing electrical components are sensitive to electrostatic discharge (ESD). Follow

ESD safety procedures while handling these parts.

8. Some products contain more than one battery. Do not disassemble any battery, or expose it to

high temperatures such as throwing into fire, or it may explode.

Product Overview

This specification describes a display device that is based on a 23.6 inch TFT LCD display

5

TV/Monitor. The part number of the panel is CMO M236H1-L01. The native resolution of the

panel is 1920 X 1080. At this resolution the monitor device can be described as WUXGA and the

television can be best described as “HDTV” or Extended Definition Television. This

television/monitor can be used to display high definition television images as images that are scaled

to the native resolution of 1920 X 1080. The television/monitor is also provided with a television

tuner as an integral part of the systems. This provision allows the monitor to function directly as a

television. It is capable of receiving off-the-air, cable, and satellite transmissions. The monitor inputs

that are provided have the ability to adapt this device to practically any consumer video source

output that is available in the marketplace. It features S-video, composite video, and component

video. The monitor computer inputs are VGA analog and HDMI(PC and HDCP). This

television/monitor provides maximum flexibility in the number of applications that it can provide

to the end user.

Customer Acceptance

1.0 SCOPE

This document establishes the general workmanship standards and functional Acceptance criteria

for LCD TV model V42L Produced by BenQ Inc.

2.0 PURPOSE

The purpose of this publication is to define a procedure for inspection of the LCD TV by means of a

customer acceptance test, the method of evaluation of defects and rules for specifying acceptance

levels.

3.0 APPLICATION

The "Customer Acceptance Criteria" is applicable to the inspection of the LCD TV, completely

packed and ready for dispatch to customers. Unless otherwise specified, the customer acceptance

inspection should be conducted at manufacturer's site.

4.0 DEFINITION

The "Customer Acceptance Criteria" is the document defining the process of examining, testing

or otherwise comparing the product with a given set of specified technical, esthetic and

workmanship requirements leading to an evaluation of the "degree of fitness for use", including

possible personal injury or property damage for the user of the product.

5.0 CLASSIFICATION OF DEFECTS

The defects are grouped into the following classes:

5.1 Critical defect

A critical defect is a defect that judgment and experience indicate is likely to result in hazardous or

unsafe conditions for individuals using, maintaining or depending upon the product.

5.2 Major defect

A major defect is a defect, other than critical that is likely to result in failure, or to reduce materially

the usability of the product for its intended purpose.

5.3 Minor defect

A minor defect is a defect that is not likely to reduce materially the usability of the product for its

intended purpose, or is a departure from established standards having little bearing on the effective

use of operation of the product.

Note: If BenQ defect undefined failure, and it judged that is reduce the merchandise ability,
BenQ CM Inform this defect. After that parties make communication and decide how to solve.

28

6.0 CLASSIFICATION OF DEFECTIVES

A defective is a product, which contains one or more defects. The defective will be classified into

following classes:

Critical defective

A critical defective contains one or more critical and may also contain major and/or minor

defects.

Major defective

A major defective contains one or more defects and may also contain minor defects but

contains no critical defect.

Minor defective

A minor defective contains one or more minor defects but contains no critical and major

defects.

7.0 EXPRESSION OF DEFECTIVES

Number of defects

Percent of defects = ------------------------------------------ X 100%

Number of products inspected

8.0 INSPECTION STANDARD

Unless otherwise specified, the inspection standard will be defined by MIL- STD-105E (ISO-2859)
SINGLE SAMPLING PLAN. Level Ⅱ is in use all the time, inspection levels are normal, reduce
and tighten.

Acceptance Quality Level

When a critical defect is found, this must be reported immediately upon detection, the lot or

batch shall be rejected and further shipments shall be held up pending instructions from the

responsible person in relevant organization.

Major Defective: AQL 0.4

Minor Defective: AQL 1.5

29

9.0 GENERAL RULES

The inspection must be carried out by trained inspectors having good knowledge of the meaning of

“fitness for use". The inspection must be based upon the documents concerning the completely

assembled and packed product when more defects appear with the same cause only the most serious

defect must be taken into account. Defects found in accessories packed with the product as

connecting cables, plugs, adapters and the like, and being inspected as a part of the complete

product, must be included in the evaluation.

The evaluation must be within the limits of the product specification and, for not specified

characteristics, be related to the design model, limit samples or judgment of a jury of experts. Faults

must be demonstrable.

10.0 TEST CONDITIONS

Unless otherwise prescribed, the test conditions are as follows:

11.0 TEST EQUIPMENTS

11.1 BenQ PCs with BenQ display adapter or other specific display adapter, which is agreed

upon by both parties

11.2 Test program by BENQ

11.3 Power saving test tool
